* path.cc (path_conv::check): Add signal protection here since retrieving info about remote shares can take some time. * path.h (check_null_empty_str_errno): Convert to a function prototype. * path.cc (check_null_empty_str): Move to miscfuncs.cc. * miscfuncs.cc (check_null_empty_str_errno): New function. (__check_null_invalid_struct): Ditto. (__check_null_invalid_struct_errno): Ditto. (check_null_empty_str): Change from VirtualQuery to IsBadWritePtr. * thread.cc (check_valid_pointer): Ditto. * resource.cc (getrlimit): Use check_null_invalid_struct macro for checking validity of pointer.
